Re: What can you do with a 48MHz C64 ?

I was able to achieve these WRITE speeds to the cart port with the following CPU speed settings... Normal (1MHz): 137k/s 2 MHz: 240.6k/s (1.75x) 3 MHz: 320.9k/s (2.34x) 4-16 MHz: 481.4k/s (3.51x) 20-48 MHz: 962.7k/s (7x) Just to be clear, there is no difference in performance between 4 and 16 MHz or...

Re: What can you do with a 48MHz C64 ?

I just discovered something pretty awesome about the Ultimate 64 in turbo mode at full 48 MHz. While the cartridge port remains operating at a normal speed (0.985 MHz for PAL and 1.02 MHz for NTSC), the CPU being so much faster allows it to perform a WRITE at almost every consecutive cycles. With a ...

Re: What can you do with a 48MHz C64 ?

At this point, I don't know if it is possible to have RAM, ROMs or IO chips plugged to the cart port of the U-64 and have them run at more than 1MHz.

If it is, I can easily see adding some of WDC's high speed W65X22N on the cart port and do some pretty amazing stuff.

Re: The Expanse - the sci-fi show to end Star Trek

... I really enjoyed the attempt at realistic space-shippery with relatively minimal handwaving. IMHO, the most interesting scene in terms of gravity/inertia realism occurs in an episode of season 3 titled 'Delta-V'. There is a young man trying to impress a girl who decides to try and fly through t...

Re: The Dos and Don'ts of using an EPROM as PLA in a C64.

Mine was just curiosity. I have no doubts whatsoever that the Plankton is the best solution available. PLAnkton EV is even better. It just seems strange that there is no other eprom with the "right" timings and voltages except those. Oh and please, don't get too "close" to the original!!! They burn...

Re: What can you do with a 48MHz C64 ?

I've been having fun running games for the C64 3D Construction Kit, namely the 3D Kit Game, Cyborg; and A Chance in Hell v1, v1.1, and v1.2. They run excellently (moving across the landscape very smoothly and quickly) at the U64's top speed of 48 MHz., especially ACIH v1.2 which has been bug-fixed/...

I haven't seen 'Away' yet but it too is reputed as having a good level of realism.

The Expanse - the sci-fi show to end Star Trek

I only recently discovered the sci-fi series 'The Expanse' and I really enjoyed it. Yes, I admit, I am guilty as charged, it's the only thing I've watched on TV for the last week. I really like this show because it presents a much more realistic version of being in space than Star Trek or any other ...
